Ngl your probably right
This chapter reveal a lot of unanswered questions. Like before we had a hint that the queen and undertaker work together but we don't know sense when and why.
But know we know that Albert was An old man before and know he young and look deferent. So it look like he was one of the first experiences and know we know how undertaker has the money and the funds to build all these projects.
So what I'm trying to say is there relationship were not recent as we thought.
Maybe they team up so the queen can resurrect albert and don't you think john is special? Maybe he is also a shinigami or undertaker's work.
bro its probably that grave keeper guy reanimating the queen's body and her guard pretending their alive to spy and shit just like Ciel's brother
